Mainalo (Greek: Μαίναλο, Ancient Greek: Μαίναλος, Μαίναλον, romanized: Mainalos, Mainalon; Latin: Maenalus) is the tallest mountain in the Menalon highlands of the Peloponnese, and is located in Arcadia.
The mountain's highest point, known as both Profitis Ilias and Ostrakina, at a height of 1,981 m (6,499 ft), is the highest point in Arcadia. The mountain has a length of 15 to 20 kilometres (9.3 to 12.4 mi) from southwest of Tripoli to northeast of Vytina, and a width of 5 to 10 kilometres (3.1 to 6.2 mi) from Zygovisti to Kapsas. The mountain is part of a Natura 2000 site, designated in March 2011, covering an area of 226.4 square kilometres (87.4 mi2). In the 19th and early 20th century, the mountain was known as Apano Chrepa.
While the mountain takes its name from the ancient Mount Mainalos, and the ancient city of Maenalus which stood at its summit, modern scholars now identify the location of the ancient mountain as "Ágios Ilías", a mountain 25 kilometres (16 mi) further south near the town of Asea. The name was likely mistakenly connected to the mountain now known as Mainalo by earlier European travelers. According to ancient Greek mythology, Mount Mainalos got its name from Maenalus, son of Lykaon, king of Arcadia, and in antiquity the mountain was especially sacred to Pan.
Mainalo is home to a ski resort, which is found at an elevation of 1,600 metres (5,200 ft), with 7 ski slopes and 4 lifts, which are at an altitude between 1,550 to 1,770 metres (5,090 to 5,810 ft).
